Bored and frustrated, a curious sister stumbles upon her brother's hidden stash of pleasure toys. Intrigued, she takes one out - a massive, realistic dildo - and begins to explore her own desires. Her brother, hearing her muffled moans, investigates and catches her in the act, his own arousal evident. They argue, but the tension is palpable. Soon, they're both naked, the sister stroking her brother's equally impressive cock as she fantasizes about replacing the toy with the real thing.
